The outcome was as follows:
From a 40 roll, all 3 of us went. Myself and the 135i immediately put 2-3 cars on the 5.0 all the way until about 110 where we had a solid 4-5 cars on the 5.0 and then we all shut down. The 135i put 1 car on me before shutting down. This was done one more time to ensure consistency and the outcome was the same.

!Disclaimer! The above was conducted in Mexico.

I have JB4 with DCI...I run map5 AutoTune how would I add E85 combined with 93 Pump? Will it make a difference? Whats the best ratio of E85/93 Pump? What map would I leave it on?

Then the drivers you've seen suck. With a bama tune, intake, headers, catback they'll run 11s all day long. Sucks that none of them could do better than 114, but I doubt they were tuned right, or something else was wrong. The Boss 302 traps 115 bone stock. They are much faster on E85 (there are several running 10s on E85 that I've seen).

I've go no doubt you did what you did, but don't let a local occurrence extrapolate into an assumption about how they all are. The N54's turbos do NOT flow enough air to keep up with a FBO 5.0 running the same gas. Just a fact of life.

awesome will def get it a shot...how does it compare to unleaded race gas 100 octane? I have both in my area lol

E85 for our cars is basically cheap race fuel. High octane, and also ethanol has a cooling effect in the combustion cylinders. My car loves it.. I run 25-30%... have been for months. Too much more E85 than say 40% and you'll probably run into fueling issues that you wouldn't get with race fuel.. but 100 octane race gas is what... $8 a gallon?

injector on cylinder 5 did go out about 4 months down the road but had nothing to do with this run. if you're not running meth or larger turbos these n54's are not powerhouse's up top.

they spool low end and make awesome torque but thats no good at a track

While I do agree that N54's with stock turbo's aren't really powerhouses up top, they certainly do hold their own. Here is a run of my friends 135i with just a tune, fmic and downpipes and still on stock runflats:
